Application
1,2,3,4,5-Pentaphenyl-1'-(di-tert-butylphosphino)ferrocene is a phosphine ligand characterized by its steric hindrance, designed to enhance the efficiency of palladium-catalyzed reactions. This pink solid is specifically employed in facilitating key transformations such as amination, arylation, and etherification of aryl chlorides, making it essential in the preparation of active palladium catalysts for forming carbon-carbon (C-C), carbon-nitrogen (C-N), and carbon-oxygen (C-O) bonds. Additionally, it is effectively utilized in the Pd-catalyzed α-arylation of azlactones, as well as esters, amides, and aldehydes, demonstrating its versatility in complex organic synthesis, including prominent reactions like the Heck and Suzuki couplings.
